Benzalkonium chloride (BAC) is commonly used as a bactericidal preservative and it may cause allergic reactions in some patients. An unusual case of anaphylactic shock in a 55-year-old woman following insertion of a central venous catheter (CVC) that was coated with BAC is presented. Assuming anaphylactic shock from the CVC, the catheter was removed immediately. Standard resuscitation was started with 100% oxygen, epinephrine, and saline infusion. The patient recovered without any sequelae. One month later, an intradermal skin test was positive for BAC.

Latent tuberculosis prevalence in healthcare workers in Laos: a cross-sectional study.

Background: Individuals with latent tuberculosis infection (LTBI) have a high risk of active infection, morbidity and mortality. Healthcare workers are a group who have increased risk of infection and onward transmission to their patients and other susceptible individuals; however, LTBI is often undiagnosed, and individuals are asymptomatic. Interferon gamma release assays (IGRA) can detect evidence of TB infection in otherwise asymptomatic individuals and are a good indication of LTBI.

Background: Risk factors for bloodstream infection in patients with COVID-19 in the intensive care unit (ICU) remain unclear. The purpose of this systematic review was to study the risk factors for BSI in patients admitted to ICUs for COVID-19.
Methods: A systematic search was performed on PubMed, EMBASE, Cochrane Library, and Web of Science up to July 2024.

Background: Emerging evidence support the notion that loss of splicing repression by TDP-43, an RNA binding protein that was first implicated in ALS-FTD, underlies their pathogenesis. Previously, we showed that delivery of an AAV9 vector at early postnatal day expressing a fusion protein, termed CTR comprised of the N-terminal region of TDP-43 and an unrelated splicing repressor termed RAVER1 complemented the loss of TDP-43 in mice lacking TDP-43 in spinal motor neurons (ChAT-IRES-Cre;tardbp mice). To translate this potential therapeutic strategy to the clinic, it will be important to demonstrate benefit of such AAV delivery of CTR to motor neurons in adult mice.

Background: Dural arteriovenous fistulas (DAVFs) are abnormal communications between dural arteries and cortical, meningeal, or dural sinus veins. They represent 10-15% of intracranial arteriovenous malformations. In rare cases, they have been associated with potentially reversible cognitive impairment and dementia.

Skeletal muscle relaxants have their place in everyday use in numerous anesthesiological procedures, such as preparing a patient for surgery, supporting mechanical ventilation, and performing effective intubation. These drugs can be divided, based on their mechanism of action, into depolarizing skeletal relaxants, such as succinylcholine, and non-depolarizing skeletal muscle relaxants. Non-depolarizing agents are further categorized, based on their structure, into steroidal (eg, rocuronium) and benzylisoquinoline (eg, atracurium) compounds.
